Method and device for sidelink communication based on parameters

Abstract

An electronic device including circuitry configured to perform communications with a road side unit (RSU), a base station, and another electronic device mounted to a moving object; receive, from the base station or the RSU, parameters for performing intermittent device-to-device (D2D) communication with the another electronic device, the parameters including information indicating a resource pool used for performing the intermittent D2D communication with the another electronic device; and perform intermittent D2D communication with the another electronic device based on the parameters received from the base station or RSU.

The invention claimed is: 
     
       1. An electronic device comprising:
 circuitry configured to 
 perform communications with at least one of a road side unit (RSU), a base station, or another electronic device mounted to a moving object; 
 receive, from the base station or the RSU, a first parameter indicating a resource pool used for performing sidelink communication with the another electronic device; 
 receive a second parameter comprising information identifying one of a plurality of groups to which the electronic device belongs; and 
 perform the sidelink communication based on the first parameter and the second parameter, 
 wherein the second parameter comprises information identifying a plurality of groups to which the electronic device belongs, each group having different parameters for performing the sidelink communication that are commonly applied to electronic devices associated with each group. 
 
     
     
       2. The electronic device of  claim 1 , wherein
 the first parameter comprises information indicating a cycle of the sidelink communication and a start timing of the cycle. 
 
     
     
       3. The electronic device of  claim 2 , wherein
 the first parameter comprises an extension parameter indicating an extension of the cycle. 
 
     
     
       4. The electronic device of  claim 1 , wherein
 the first parameter comprises identification information indicating a group of electronic devices having common sidelink communication parameters to which the electronic device belongs. 
 
     
     
       5. The electronic device of  claim 1 , wherein
 the circuitry is configured to acquire the first parameter from the RSU. 
 
     
     
       6. The electronic device of  claim 1 , wherein each group has different first parameters for performing the sidelink communication that are commonly applied to electronic devices associated with each group. 
     
     
       7. A method comprising:
 performing communications with a road side unit (RSU), a base station, and another electronic device mounted to a moving object; 
 receiving, from the base station or the RSU, a first parameter indicating a resource pool used for performing sidelink communication with the another electronic device; 
 receiving a second parameter comprising information identifying a plurality of groups to which the electronic device belongs; and 
 performing the sidelink communication based on the first parameter and the second parameter. 
 
     
     
       8. The method of  claim 7 , wherein
 the first parameter comprises information indicating a cycle of the sidelink communication and a start timing of the cycle. 
 
     
     
       9. The method of  claim 8 , wherein
 the first parameter comprises an extension parameter indicating an extension of the cycle. 
 
     
     
       10. The method of  claim 7 , wherein
 the first parameter comprises identification information indicating a group of electronic devices having common sidelink communication parameters to which the electronic device belongs. 
 
     
     
       11. The method of  claim 7 , further comprising
 acquiring the first parameter from the RSU. 
 
     
     
       12. The method of  claim 7 , wherein each group has different first parameters for performing the sidelink communication that are commonly applied to electronic devices associated with each group.
